Application filed November 26, 1923.

To all whom it may concern:

Be it known that I, MICHAEL ROTH- HIRSCH, a citizen of the Republic of Austria, residing at Vienna, Republic of Austria, have invented certain new and useful Improvements in Valves for Inflatable Bags for Footballs, of which the following is a specification.

Valves for inflatable bags for foot balls have already been proposed in which a conical or spherical valve body of rubber is permanently held against the correspondingly shaped valve seat by elastic cords or tapes. Such valves show the drawback that the cords or tapes lose their elasticity after some time and then do not hold the valve body on its seat with a force required for tightly closing the valve.

The object of my invention is to obviate this drawback and with this object in view to provide a valve for the inflatable bags of foot balls and similar articles in which the conical valve body of rubber co-operating with a conical valve seat is freely suspended on and secured to a cord or tape passing through narrow openings in the flexible tube of the bag to the outside thereof, so that the valve may be closed by hand. I

In the annexed drawing an embodiment of my improved valve is shown by way of example in vertical central section.

In the inflatable rubber bag 1 there is secured at its opening a rubber block2 of any desired shape preferably by being Vulcanized into the bag, a conical recess 3 provided in the block and in permanently open communication with the flexible tube 5 serves as the valve seat. The tube 5 is secured to the outside of the bag, preferably by means of an intermediate rubber plate 4- opposite the block 2 in the usual manner. The conical valve body 6 within the bag is freely suspended on and secured to a cord or tape 7, preferably a double cord or tape, passing through small openings in the sides of the flexible tube 5 to the outside thereof. The cord or tape 7 enters the central bore 8 in the valve body and is secured to a transverse pin 9, for instance by being wound round the same. The inner end of the bore 8 is tightly closed by a plate 11 secured to the inner end of the valve body. For preventing the cord or tape 7 to fully slip into the flexible tube, any suitable 5 means such as a button may be attached to Serial No. 677,029.

its outer end. If, as shown, a double cord or tape 7 be used it is suflicient to knot the outer ends together on the outside of the flexible tube 5.

When it is desired to inflate the bag, any usual inflating pump or source of air under pressure is connected with the outer end of the flexible tube 5, the air under pressure forces the valve body 6 off its seat 3 while the cord or tape 7 prevents it from entirely falling into the bag. After pumping up the bag to the desired extent the valve is drawn against its seat by the cord or tape 7 and then the air pressure within the bag holds the valve firmly in the closed position, when P the pump or source of air under pressure is disconnected from the flexible tube. When the bag has to be deflated it is only necessary to push the valve away from its seat into the bag by means of a piece of wire or a small rod introduced into the flexible tube 5 through its outer opening. In pumping up the bag it is advisable to push the nozzle of the pump or connection to the source of air under pressure so far into the flexible tube that the openings 10 are covered,

What I claim is:

1. In a valve for inflatable bags for footballs a valve seat within the bag, aflexible tube in permanently open connection with the opening of the valve seat and leading to the outside of the bag, a valve body adapted to close the said opening in the valve seat,

a cord secured to the valve body and passing through the said flexible tube and openings in the latter to the outside thereof and means on the said cord for preventing its outer end to slip into the flexible tube.

2. In a valve for inflatable bags for footballs, valve seat within the bag, a flexible tube in permanently open connection with the opening of the valve seat and leading to the outside of the bag, a valve body adapted to close the said opening in the valve seat, a double cord secured to the valve body and passing through the said flexible tube and openings on opposite sides of the flexible tube to the outside, the outer ends of the said double cord being knotted together outside the flexible tube.

8. In a valve for inflatable bags for footballs a valve seat within the bag, a flexible tube in permanently open connection with the opening of the valve seat and leading to the outside of the bag, a valve body adapted to close the said opening in the double cord being knotted together outside valve seat a double cord threaded through the flexible tube. 10 a bore in the valve body and secured to the In testimony whereof I have afiixed my latter, means for hermetically closing the insignature in presence of two Witnesses.
